CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 405,285, dated June 18, 1889.

Application filed February 5, 1889. Serial No. 298,755. (No model.)

To @ZZ whom it may concern:

Beit known that I, MARTIN L. UNGER, a citizen of the United States, residing at Nelson, in the county of Nuckolls and State of Nebraska, have invented new and useful Improvements in Oar-Couplings, of which the following is a specilication.

My invention relates to improvements in car-couplings; and it consists in certain novel features hereinafter described and claimed.

In the accompanying drawings, Figure l is a perspective view of a car-coupling constructed in accordance with my invention. Fig. 2 is a longitudinal vertical section, and Fig. 3 is a transverse vertical section of the draw-head.

Referring to the drawings bylet-ter, A designates the end of the car, and B' the drawhead, secured thereto in the usual manner. The draw-head is hollow, and is provided with an interior Jtransverse partition O, and in its side walls, at the top and bottom of t-he same, has the longitudinal grooves D, as shown. From the upper side of the draw-head, at the yfront end of the same, a stop E depends into the path of the sliding block.

F designates the sliding block, provided on its sides with the longitudinal ribs G, which engage the grooves D, and having a recess G in its front end to receive the end of the link. From the rear end of this sliding block a stem or rod H projects through the transverse partition C in the draw-head, and around this stem, between the rear end of the sliding block and the transverse partition, a springl is coiled, so as to bear against the sliding block and force it normally toward the front end of the draw-head.

On the upper side of the draw-head, at the front end of the same, I provide the vertical in its proper position.

A chain or cable O is secured to the upper end of the coupling-pin, and extends upward over the pulley K and then rearward to a rotary rod on the end of the car.

P designates the rotary rod, which is mounted vertically on the ends of the car, and has the end of the cable O secured to its lower portion. A spring Q is secured to the end of the car and wrapped around the sauid rod, so that after the said rod has been operated to raise the coupling-pin the spring will return it to its initial position in order to allow the coupling-pin to fall. R designates a pulley mounted onthe top of the car at the end of the same, and S is a cable secured to the rod P and passing over said pulley. The cable S passes along the top of the car to the opposite end of the same, and a shorter cableT is connected thereto and extends down the side of the car.

Vhen the parts are uncoupled, the sliding block will be at the front end of the draw-head and the coupling-pin will be resting thereon. When the cars are to be coupled, the link is securedin one draw-head and the two cars then brought together. As the link enters the stationary draw-head, it will contact with the sliding block to push the same backward, allowing the coupling-pin to fall by gravity into engagement with the link. The ears are uncoupled by rotating the rod P, so as to raise the coupling-pin, thereby allowing the coupling-link to be released from the draw-headl The device can be uncoupled from the top or i side of the car and from either end.

From the foregoing description it will be seen that I have provided a very compactlyarranged and simple car-coupling, which is very eiicient in operation. The recess in the front end of the sliding block holds the link The longitudinal ribs on the sliding block and the grooves in the draw-head give the sliding block a positive movement, so that the proper operation of the device is insured. The frame in which the coupling-pin works protects the said pin against injury, and also guidesit in its movements, so that it will always engage the link when lowered.

Having thus described lnyinvention, what-I claim, and desire to Secure by Lett-ers Patent, 1S

l. The combination of the draw-head, the vertical frame erected thereon, the transverse roller in the upper end of the frame7 the ooup ling-pin moving in the vertical frame and having a eross-head N bearing against the sides of the Vertical frame, the Vertical rotary rod arranged in rear of the Vertical frame, and the cable Secured to the eouplingph, passing over the roller and connected to the rotary rod, as set forth.

2. The combination, with the ear and the draw-head, of the rotary rod mounted on the ear, the spring secured to the ear and wrapped around the said rod, the pulley on the upper side of the car, the Cable secured to the rod and passing around the pulley, the Vertical frame on the draW-l1ead, the Coupling-pin moving in said frame, and the cable connecting the pin With the rotary rod, as set forth.

In. testimony that I claim the foregoing` as myown I have hereto afxed my Signature in presence of two Witnesses.
